Onkyo TX-NR686 review

Features

In addition to the main 7.2 channels - the last two of which can be used both for the rear and for the speakers of the “upper” channels in the Dolby Atmos or DTS setup: X - TX-NR686 is equipped with additional amplification channels for connecting a pair of speakers in the second zone. And given the receiver's output power, which is 165 watts per channel (6 ohm), even with fairly demanding acoustics, it should not have any problems.

Design and build

The TX-NR686 outperforms most of its competitors and, given the built-in 384 kHz / 32-bit DAC, saves a little while organizing a stereo system in another room. The Onkyo TX-NR686 is THX Select certified, reflecting its superior cinema performance. To obtain the most dynamic and rich sound while maintaining the comparatively compact dimensions of the case, this seven-channel AV receiver is equipped with amplifiers made using Dynamic Audio Amplification technology. Due to the high output current, which is provided including through the use of a custom transformer H.C.P.S. in the power supply, Onkyo TX-NR686 is able to fully swing even 4-ohm speakers. The audio circuit of the device also uses the VLCS system to eliminate high-frequency noise, and its circuitry eliminates the phase shift of the signal to maintain sound transparency.

Connectivity

The device has a good set of physical inputs, it has seven HDMI connectors with HDCP 2.2 support (one of which is located under the volume control on the front panel), two optical and one coaxial digital inputs, a USB port, six analog inputs (including 3.5 mm front panel jack) and MM Phono input for connecting a turntable.

Setup

The AccuEQ auto-tuning system takes into account the location and type of speakers mounted on the ceiling using the AccuReflex function. If instead of ceiling speakers models based on reflections and installed in the frontal plane are used, the system will take this into account and adjust the signal phase accordingly.
